Our standard production consists of 40 (+/- 2) density polyurethane injected locked panels of which the top surface is 10 mm thick plywood and bottom surface is galvanized sheet. Ribbed surface panels come in 7 different thicknesses, same as in the case of wall / ceiling panels. Ribbed panels have a load capacity of 2,000 kg/m2 and non-slip CrNi or 200-micron PVC coated steel sheet can optionally be used on top of the plywood.
